Spin-orbit coupling mediated photon-like resonance for a single atom trapped in a symmetric double well
Changwei Fan, Xiaoxiao Hu, Xin Yan +5
We employ a method involving coherent periodic modulation of Raman laser intensity to induce resonance transitions between energy levels of a spin-orbit coupled atom in a symmetric…
Controlled pumping of matter-wave solitons in a one-dimensional optical superlattice
Xiaoxiao Hu, Zhiqiang Li, Ai-Xi Chen +1
We study the pumping of matter-wave solitons formed in Bose-Einstein condensates (BECs) with attractive atomic interactions that are loaded into optical superlattices in which one…
Chaos signatures of current phase transition in a toroidal trap
Zhiqiang Li, Xiaoxiao Hu, Zhao-Yun Zeng +3
In this work we demonstrate how the directed motion of atomic Bose-Einstein condensates in a toroidal trap can be controlled by applying a zero-mean oscillatory driving field. We s…
Ratchet current in a -symmetric Floquet quantum system with symmetric sinusoidal driving
Zhiqiang Li, Xiaoxiao Hu, Jinpeng Xiao +2
We consider the ratchet dynamics in a -symmetric Floquet quantum system with symmetric temporal (harmonic) driving. In the exact phase, for a finite nu…
Scattering of one-dimensional quantum droplets by a reflectionless potential well
Xiaoxiao Hu, Zhiqiang Li, Yu Guo +2
We investigate, both analytically and numerically, the scattering of one-dimensional quantum droplets by a Pöschl-Teller reflectionless potential well, confirming that there is a s…
